HANDLE-BAR FOR BICYCLES.

SPECIFI CATION forming part of Letters Patent No. 615,868, dated December 13, 1898.

Application filed September 10,1897- filerial No- 651,189. (No model.)

T0 at whom it may 0011100771,.-

Be it known that I, WILLIAM A. MARBACH, a citizen of the United States, residing at Cleveland, in the county of (Juyahoga and State of Ohio, have invented certain new and useful Improvements in Handle-Bars for Bicycles, of which the following is a specification.

This invention relates to handle-bars for bicycles, and has for its object to provide a cushioned handle-bar whereby the jarring is avoided and the hands and arms of the rider are relieved from its injurious effects.

The invention consists in hinging or pivoting the handle-bar to the bar-stem and in rovidin a s rin -bearin in the stem act p b b 6 ing upon the handle-bar for accomplishing the said results.

It also consists in the means for nicely adjusting the inclination of the handle-bar.

The invention is constructed and arranged to operate substantially as hereinafter described, and pointed out in the claim.

Int-he accompanying drawings, Figure l is a side elevation, partly in section, of my new handle-bar joint, showing the hinge, the spring, and the adjusting attachments, Fig. 2 is a transverse vertical section of the same. Fig. 3 is a front side elevation, and Fig. at is a rear side elevation, of the handle-bar and the new joint.

A represents a handle-bar stem which is secured to the fork-stem. B is a head-plate attached to the top end of said stem A, provided with end flanges b b. O is a plate also having end flanges c c, which fit inside of the flanges b b of the head B. D is a bolt placed through eyes in the said flanges which joins the head B and plate 0 firmly together and which constitutes ahi'nge-joint. To the plate 0 the handle-bar E is attached by means of a clip F.

f f are lugs on the corners of the clip, which catch under lugs or projections f" f on the front side of the plate 0. The opposite side of the clip has a lip F, which stands a short distance above the plate and through which bolts g g are placed'and are screwed into the plate C, thus forming a clamp for holding the is formed an annular half-round screw-threaded groove 6. I is a screw fitted to lie in the recess h and have its upper side mesh with the screw-threads in the said groove 6. The screw is retained in place by the front side of the clip F and in which is made a round hole 1' of less diameter than the screw, through which a screw-driver may be inserted for turning the screw when required.

J is a rod or bolt having its head held in a seat in the plate 0. The bolt passes down through a hole in the head-plate B into the hollow stem A, and its lower end is screwthreaded and carries a nut K. S is a spring on said bolt, bearing against and between the head 0 and the nut j, which comprises a bearing for the handle-bar.

The operation of this improvement is as follows:' The pressure upon the handles by the rider depresses them. This causes a contraction of the spring and dispels the rigidity of the bar-support, and thereby destroys the jarring effects upon the hands and arms of the rider.

Having described my invention, I clain1- In a bicycle handle-bar, a hollow stem A, a plate B on said stem, flanges b b on the ends of said plate B, a plate C having flanges c 0 bearing against the inside faces of the flanges b b, a bolt D passed through said flanges, a clip F, having lugs f f catching under lugs f f on the plate 0, a lip F on said clip, bolts 9 9 through said lip F and screwed into the plate 0, a bolt J having its head held in a seat in the plate 0, said bolt J extending through the plate B and down into the hollow stem A, a spring S on said bolt J below the head, and a nut K on the lower end of the bolt and bearing against the lower end of the spring, all constructed and adapted to operate substantially as described.

WILLIAM A. MARBAoII.
